NEET BIOLOGY

Detailed explanation-1: -Plants provide oxygen for us and all the other animals. Through photosynthesis they absorb carbon dioxide and release oxygen which gives us the air that allows all animals on the planet to breathe. Plants are an essential part of the water cycle.

Detailed explanation-2: -Green plants convert carbon dioxide and water into food compounds, such as glucose, and oxygen. This process is called photosynthesis. Plants and animals, in turn, convert the food compounds by combining it with oxygen to release energy for growth and other life activities.

Detailed explanation-3: -During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.

Detailed explanation-4: -Once they have water and carbon dioxide, they can use energy from sunlight to make their food. The leftovers from making the plant food is another gas called oxygen. This oxygen is released from the leaves into the air.

Detailed explanation-5: -Plants are important for the survival of living organisms as they absorb CO2 and release O. They are also the main producers of food because of the presence of chlorophyll pigment. They provide us with day-to-day life things such as wood, timber, paper, etc.
